Well, Hello Rich Murray, BS physics, MA psychology!
Haven't heard much from you since I left sci.physics.fusion (14 years
ago?) and all the rancor and confusion there.
I have the utmost regard for Robert Foot and his theories. I am
surprised you are in a collaboration with Robert Foot. Or do I have
a misimpression from your post?
The following may be of interest to you, as they are intimately
related to Robert Foot's work:

Exotic meteoritic phenomena: The Tunguska event and anomalous low
altitude
fireballs -- manifestations of the mirror world?
R. Foot, T. L. Yoon
(Submitted on 11 Mar 2002 (v1), last revised 10 May 2002 (this
version, v5))
There are a number of very puzzling meteoritic events including
(a) The Tunguska event.
It is the only known example of a low altitude atmospheric explosion.
It is also the largest recorded event.
Remarkably no fragments or significant chemical traces have ever been
recovered.
(b) Anomalous low altitude fireballs which (in some cases) have been
observed to hit the ground.
The absence of fragments is particularly striking in these cases,
but this
is not the only reason they are anomalous.
On the other hand, there is strong evidence that most of our galaxy
is made
from exotic dark material - `dark matter'.
Mirror matter is one well motivated dark matter candidate, since it
is dark
and stable and it is required to exist if particle interactions are
mirror
symmetric.
If mirror matter is the dark matter, then some amount must exist in
our
solar system.
We demonstrate that the mirror matter theory allows for a simple
explanation
for the puzzling meteoritic events [both (a) and (b)] if they are
due to
mirror matter space-bodies.
A direct consequence of this explanation is that mirror matter
fragments
should exist in (or on) the ground at various impact sites.
The properties of this potentially recoverable material depend
importantly
on the sign of the photon-mirror photon kinetic mixing parameter,
"epsilon".
We argue that the broad characteristics of the anomalous events
suggests
that "epsilon" is probably negative.
Strategies for detecting mirror matter in the ground are discussed.
